xnited gime To lilall whom 'it nmy concern le it known that I, WlLLIAM P. SKIFFINGTON, of New York, in the county and State ,of N ew York,

lliave inveutedncertain new and useful ImprovementsA in"iSteamBoiler, of4 which' the following is a. specification; l 1. i v

Eigurc I represents-a longitudinal horizontal seo tioii of a Vsteam-boiler embodying myinvention.

`Figure II is a cross-section. 1 Eigure III isa vert-icallongitudinal section of parts ofboiler." i i lifyinrention-` consists in the construction of square boites A, each box haring `a`ll the` ends of the tubes which bolts 't' pass to screw one box to the other box.

Besides these openings n, and on, an opening, x, is made at the nl of each `boiqcxtending nearly the whole length of the box, or the width of one` row of tubes, and closedby a suitable plate or cover, h. ,'llhe tubes may be fastened 1u various way tothese boxes, but I prefer to attach to the ends of the. tubes `B `til-anches a, and to fasten'the same, by means ot' bolts, against the boxes A.

Byv this arrangemennthe circulation of the water @anni @time WILLIAM P. SKIFFINGTON, or NEW YORK, N. Y. l

Leners Patent No. 103,248, ma May 17, 1ero.

i IMPRQVEMENT n; STEAM-GENERATQRS.

The Schedule referred to in these Letters-Patent andy making part of the same.

' and steam at the ends of the tubes in those boxes will not be confined or obstructed, as the area of the openings n and m will be larger than the area ofseverai of' thetubes, and the tubes can be easily cleaned and repaired 'through the doors or covers h..

In the manufacture of boilers after this plan the" 4number oi' pieces is reduced, and, as each row of tubes forms a complete part, the required size of' a boiler can be readily obtained by increasing or diminishing `the number of rows. v

The box on the upper or lower row may either be made with the upper-or lower ends cast in solid, or by fastening suitable covers to the same.

The sides and top of the boiler or lire-roon1 are formed by brick-work, as represented in Figs. I and II. i Y .v What I claim as my invention, and desire to secure by Letters Patent, isi The arrangement of `boxes A with openings 11pm, and sc, the latter opening being closed by a suitable plate or coter, h, in combination with aseries of tubes, B,.and constructed substantially as and for the pnr pose herein described. g i,
